Johnson & Son Electric Company in Baltimore: Licensed Residential and Commercial Work with Same-Day Service
Johnson & Son Electric Company is a licensed electrical contractor serving Baltimore's residential and commercial properties, offering panel upgrades, rewiring, fixture installation, and troubleshooting on a same-day or next-day basis depending on job complexity and current demand.
What Johnson & Son Electric Company actually is
A full-service electrical firm operating in Baltimore for decades, Johnson & Son holds Maryland's required Class A electrical contractor license and performs work subject to city permit and inspection. The company handles both new construction and retrofit work in homes and small commercial spaces, from single outlet repairs to complete panel replacements. Owner and lead electrician John Johnson manages most jobs personally, which affects scheduling availability but typically means direct accountability.
Services and pricing
Standard service calls run $85 to $120 for diagnosis (credited toward repair if work proceeds). Fixture installation, outlet addition, and light switch replacement typically cost $150 to $350 per fixture depending on location and existing wiring condition. Panel upgrades from 100-amp to 200-amp service run $2,500 to $4,200 including permit and inspection, with the spread reflecting whether existing conduit can be reused. Whole-home rewiring in a 1,500-square-foot Baltimore rowhouse averages $4,800 to $7,500. Verify current pricing by phone; labor rates can shift seasonally, and material costs fluctuate.
The company charges a travel fee of $35 within Baltimore city limits and does not require deposits for service calls, though larger jobs typically need 50 percent down.
How it compares to other Baltimore electricians
Monumental Electric, a larger outfit with multiple crews and a dedicated estimator, typically schedules 5 to 7 days out but handles volume faster once booked; their minimum service call is higher at $150. Charm City Electrical advertises same-day response but operates primarily north of Fells Point and rarely takes jobs south of downtown. Johnson & Son's advantage lies in owner-led work on moderate-complexity jobs (panel upgrades, rewiring, major fixture work) where continuity matters, and in faster scheduling during off-peak weeks. For large-scale commercial builds or jobs requiring multiple crews simultaneously, Monumental is better equipped.
Who this suits and who it does not
Johnson & Son works well for homeowners seeking licensed, accountable service on rowhouse electrical issues, aging panel problems, and kitchen or bathroom upgrades. The owner's hands-on approach suits customers who value explaining work step-by-step and don't need a call center intermediary. It is less ideal for landlords managing multiple properties who need monthly billing cycles or clients requiring work during evenings or weekends on short notice; the company operates Monday through Friday, 7 a.m. to 4 p.m., and does not staff emergency weekend callbacks.
What the first visit involves
Call for a diagnostic appointment during business hours. Johnson or a licensed crew member will inspect the issue, walk through the relevant code requirements, and provide a written estimate before starting work. Most service calls conclude the same day if materials are standard stock; specialty items like certain dimmer modules or outdoor-rated fixtures may require a second visit. Permit and inspection needs are discussed upfront; the company covers submission and scheduling.
Hours, location, and logistics
Johnson & Son operates from a shop in West Baltimore at 4217 Gwynn Oak Avenue, accessible by car with street parking. Hours are 7 a.m. to 4 p.m. Monday through Friday; no Saturday service. Phone estimates are offered but in-person inspections are required before a firm quote on renovation work. The company maintains active licensing with the Maryland Department of Labor, Licensing and Regulation; verify current status or get a recommendation through Baltimore's Department of Housing and Community Development, which publishes licensed contractor lists.
Johnson & Son occupies a narrow tier of Baltimore electrical work: reliable, owner-present, licensed, and affordable enough for residential jobs too small for Monumental but needing more than a handyman's scope. For rowhouse owners and modest commercial tenants, the difference between this company and a larger outfit often comes down to scheduling preference and how much direct communication matters.
